Best use cases for Ryno vs. MH Build PET

I bought a roll of MH Build PET and a roll of Ryno, and they both print very nicely. I think I've found my new go to place for filament. I printed a fan duct from both materials, though, and aside from the Ryno having a bit duller surface, they don't seem a whole lot different from each other. In what sort of situations would Ryno be a better choice than MH Build?
